otherwise secured lugs 17 having outstanding hinge-pintles 18, whichlatter work in oblong or elliptic apertures 19 in the side yportions ofthe frame 10. The apertures are inclined in the direction of theirgreater dimensions. or major axes, the inclination being inward. On theinside of the frame 10, the topk and side portions thereof have a rib 20which is spaced from the front of the frame a distance to accommodatethe wall or door 15, a rabbet 21 beingy thus formed in which the doorseats when it is shut, thus bringing the same flush with the outersurface of the iange 13.
